Six specimens, of Gocldostyla saranganica Mollendorff Cat. No. 

 195405, U.S.N.M., received from the von Mollendorff collection, come 

 from Balut Island, one of the Sarangani group. These yield the fol-

Cochlostyla saranganica Mollendorff is not OocJilostyla indusiata 

 Pfeiffer, as supposed by Hidalgo. That is quite a different species 

 and comes from Tukan Bessi, an island southeast of Celebes.
